Abstract

Condensateur comportant au moins deux électrodes 2, 3, séparées par un diélectrique élastique en caoutchouc et/ou matière plastique, pour la mesure de forces exercées sur une des électrodes par détection de la variation de capacité résultante. Le diélectrique 4 est précontraint et comporte de préférence des cavités 5.Capacitor comprising at least two electrodes 2, 3, separated by an elastic dielectric made of rubber and / or plastic, for measuring the forces exerted on one of the electrodes by detecting the resulting variation in capacitance. The dielectric 4 is pre-stressed and preferably comprises cavities 5.
